01

Opening, closing and everyday use

The window has two outward-opening side-hung sashes. When operated, the sashes move away from the room. This can suit situations where you want to keep the internal area near the window clear of inward-swinging leaves. Even so, the specified opening direction should always be assessed in relation to the installation location and your usual routines.

For everyday use, operate the selected handle steadily and with control. Guide each sash when opening and closing rather than allowing it to move freely. Careful use helps keep the timber finish, glazing, seals and hardware in good condition. Remove visible dirt with suitable gentle products; avoid aggressive or abrasive cleaning methods.

The handle is an orderable design feature. It shapes the direct feel of operation and remains visible on the room side. Include your preferred handle finish with the timber species, colour and glazing-bar layout. This design choice is separate from the specified hardware components: SPILKA and IPA identify the intended fittings, not alternative brands available to choose.

Also consider how often the window is likely to be used and who will operate it. These points do not alter the fixed opening arrangement, but they help place the handle choice within your everyday use. After installation, check regularly that the window operates as intended and that seals and hardware areas are visibly clean. If operation becomes unusual, investigate the cause instead of forcing a sash.

With a two-sash unit, the operating sequence also matters in daily use. Ask for the opening and closing procedure for your particular configuration. This helps everyone using the window understand the intended handling and operate both sashes in a controlled way.

02

Construction, section sizes and technical details

The outer frame section is specified as 105 × 57 mm and the sash frame as 76 × 65 mm. These component dimensions are different from the made-to-measure dimensions of the finished window. For your enquiry, provide carefully taken project measurements and clearly identify every value on a labelled sketch.

Installation holes are specified at 14 mm. Assess the installation situation as a whole, as the wall construction, junctions and adjoining elements all need to be included in planning. The named hardware components are from SPILKA and IPA. These names describe the specified fittings; they do not offer a choice of hardware brands when ordering.

The window is available with 2- or 3-pane insulating glass. Both glazing constructions include a heat-reflective coating, a CHR warm edge spacer and argon gas fill. The glazing seals are black rubber. State clearly whether you require the 2- or 3-pane option.

This window is CE marked and offered with a 5-year guarantee. These details form part of the specified product configuration. For project records, retain the product name alongside the selected features so that technical information is not accidentally confused with that for a similarly named window type.

Pine and oak are available for the frame. You can also select made-to-measure manufacture, colour and handle finish. The technical details provide the common product basis, while these orderable features define your individual configuration. This keeps fixed construction characteristics clearly separate from personal design decisions.

05

Assessing the intended opening carefully

Because the sashes open outwards, assess the proposed window opening spatially as well as measuring it. Look at the area directly outside the window and trace where the sashes would travel when opened. Relevant features may include a deep external sill, façade projections, balustrades, downpipes, shutters, planting or other permanently installed elements.

Include exterior areas that are used regularly. If the opening faces a patio, narrow path or place where objects are commonly stored, sash movement may affect everyday use. Consider the actual location realistically, taking account of both fixed features and how the outdoor area is normally used.

Measurements need to reflect the real building condition. Take the opening at several suitable points and record noticeable variations rather than assuming a perfectly square or even shape. Clearly distinguish building-opening dimensions from the required finished window size. The stated outer-frame and sash-frame dimensions do not replace project-specific measurement.

Pay attention to adjacent finishes and junctions as well. Render edges, cladding, sills and construction transitions can affect how the window is positioned. When replacing an existing window, its visible external dimensions may not describe the entire opening. A clear sketch with unambiguous measurement references can prevent misunderstandings in an enquiry.

Photographs of the opening can provide useful additional context, but they do not replace precise dimensions. Note from which side each image was taken and which adjoining building elements it shows. Assess the area under realistic conditions, including changes caused by movable or seasonal elements. This treats the outward sash movement as part of the installation situation from the outset.

06

Bringing timber, colour and lines into one design

The visual result comes from the interaction of the paired-sash form, timber species, colour, handle and glazing-bar pattern. Pine and oak are available. Both can contribute to a historic-oriented design, but should be considered alongside the building’s existing timber elements, finishes and colour tones.

Colour is an orderable part of the configuration. It allows the window to relate to an existing façade scheme or become a deliberately distinct feature. Consider broad surfaces such as render or timber cladding, as well as smaller details on doors, eaves and other windows. A colour can appear differently according to surrounding materials and light conditions.

The glazing-bar arrangement sets the rhythm within the sashes. Horizontal lines can relate to façade bands or divisions in neighbouring windows. Vertical lines can support an upright composition. Combined grids appear more subdivided, while the bar-free view remains calmer. The key is to select one named design and provide its full title.

The handle also belongs to the visible composition on the room side. As a handle finish can be selected, decide on it together with colour, timber and glazing-bar pattern. SPILKA and IPA hardware brands should be viewed separately: they identify installed fitting components, not a choice between different manufacturers.

For a coordinated result, it can help to prepare a small project schedule for materials and colours. Record the selected timber, preferred colour, handle finish and full glazing-bar design name. Add notes about neighbouring building elements where their design is to be echoed. This lets you assess the individual choices as a coordinated window composition and communicate your requirements clearly to us.

Placing related window types and patio doors

Alongside this two-sash casement window, the range includes other windows and patio doors for different installation situations. First compare the product type and opening direction. Then consider whether you need two movable sashes, a fixed-light and sash combination, a roof window or a patio door. You can then compare materials, glazing and design options within the suitable product group.

The “Historic-style outward-opening Kombi casement window” pairs one fixed glazed light with a sash and offers several glazing-bar patterns. By contrast, the “Pivot roof window” belongs to the roof-window range and has its operating handle at the bottom. Both use a different basic construction from this two-sash casement window.

For windows with a vertical pivot axis, single- and two-sash pivot windows are available for comparison; both open outwards. If the sashes need to open into the room, compare the single- or two-sash inward-opening windows instead. Pay particular attention to the different opening and tilt functions, and to the materials and glazing-bar patterns stated for each.

For ground-level access outdoors, you can also consider the single-sash outward-opening patio doors. A historic-style version is available alongside the general design. Both product groups offer glazed designs and, depending on the design, versions with panels. Compare the door design, material options, glazing and locking with the needs of your project.

Identify the intended use first: standard window, roof window or patio door. Then compare opening direction, sash count and any fixed light, followed by timber species, aluminium cladding, glazing and available bar layouts.

Preparing your enquiry in clear steps

Begin with an unambiguous project description. Use the full name “Historic-style two-sash outward-opening side-hung window” so the required product is not confused with a pivot window, an inward-opening window or a patio door. Also note the room or façade side where the window is planned if this allocation is useful for your project.

Then add the carefully measured dimensions. A labelled sketch can show what each value refers to. Mark particular features of the existing opening and distinguish the building opening from the desired finished size. If you are enquiring about several windows, give every position its own consistently used reference so information is not mixed up.

Next define the visual features. State pine or oak, describe the required colour and specify your handle selection. Copy the exact name of the intended glazing-bar design. This makes clear whether you need a bar-free, horizontally divided, vertically divided or combined appearance.

Add your choice of 2- or 3-pane insulating glass. Keep this detail in the same schedule as the other product features. Images of existing windows or façade details can clarify your design reference; label the element they illustrate, such as the line arrangement or colour direction.

Finally, check all details for completeness and inconsistencies. The product name, dimensions, timber, colour, handle, glazing and full design name should be clearly assigned. Gather additional questions in a separate section. This compact sequence creates an understandable basis for discussing your enquiry in a focused way.

Is the window available made to measure?

Yes. The window is available made to measure. For a clear enquiry, carefully measure the intended opening and also state the required timber species, colour, glazing, handle finish and glazing-bar design.

Which timber species can I choose?

Pine and oak are available. Both form part of the specified product configuration. Consider which timber best suits your project by looking at the desired interior character, existing building elements and design concept.

Can I choose the window colour?

Yes. Colour selection is one of the orderable features. You can coordinate the timber window with a historic façade, existing timber elements or a deliberately independent colour scheme. State the required colour in your enquiry.

Is there a choice of handles?

Yes. The handle finish can be chosen for the configuration. State your preferred version with the other design features. The named hardware brands instead identify installed components and should not be understood as freely selectable brand alternatives.

How long is the window guarantee?

The two-sash casement window has a five-year commercial guarantee. Record the exact product name and selected configuration for clear identification. The guarantee does not limit any rights or remedies that apply under Australian Consumer Law.

Must the window be ordered with glazing bars?

No. You can select a version without glazing bars. Several defined glazing-bar patterns with horizontal and vertical lines are also available. This lets you configure the division to suit the intended historic façade arrangement.

What should I consider about outward opening?

Assess the opening direction at the actual installation site. Allow for adjoining building elements, sills, balustrades, planting, drainage features and outdoor areas in regular use. Include seasonal changes in the immediate surroundings.

Which glazing is available for the window?

You can choose 2- or 3-pane insulating glass. Both options include a heat-reflective coating, a CHR warm edge spacer and argon gas fill. State the required glazing construction clearly in your enquiry.
